Color

The diamond color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones stones of established color value.

Cut

Diamonds are prominent for their capability to transmit light and sparkle so intensely. Many
times, we think of a diamond’s cut as the shape, such as heart, round, square, pear, when
truly a diamond’s cut grade is how well a diamond’s facets interact with light. The cut
grade’s range from excellent, very good, good, fair, all the way down to poor.

Carat

According to GIA, “Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams.

Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the
hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by
its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats
as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats
and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’”
